About Fideliya and Modular JavaScript

In their own words, as submitted to SaaSHub.

Fideliya
Modular JavaScript

Fideliya Pass is wallet-native loyalty software for coffee shops, bakeries, salons, spas, gyms and small restaurants. Instead of a paper stamp card or an app nobody installs, each customer carries the business's own branded card in Apple Wallet or Google Wallet, and it updates itself the moment...

Features and specs

What each product offers, as listed by its team.

Fideliya 15 features
Modular JavaScript 5 features
  • Push Notifications

  • Gift Cards
    Branded digital gift cards customers can buy, send, and redeem from their phone.

  • Real-Time Updates
    Points, stamps, rewards, and tier status that update in real time on the customer's phone.
  • Analytics
    See who your regulars are, who is slipping away, and what is bringing them back.

  • Customization Options
    Build a pass that looks like your business using a premium theme library, not a generic template.
  • Team Access
    Invite your staff with the right permissions to scan and run the day to day.
  • Improved Code Organization
    Modular JavaScript allows developers to break down code into smaller, manageable modules. This enhances code readability and maintainability by organizing related functionality together.
  • Code Reusability
    Modules encourage reusability by allowing the same piece of code to be used across different projects or multiple areas of the same application, reducing redundancy.
  • Scalability
    As the application grows, managing code becomes easier with modular JavaScript. Each module can be developed, tested, and maintained independently, making the codebase more scalable.
  • Encapsulation
    Modules provide encapsulation, preventing variables and functions from polluting the global namespace. This reduces the risk of naming conflicts and bugs.
  • Improved Testing
    With code organized into discrete modules, writing unit tests becomes more straightforward. Each module can be tested individually, leading to more reliable and maintainable tests.

Possible disadvantages

  • Increased Complexity
    Introducing modularity can add complexity to the build process, as it often requires module loaders or bundlers (like Webpack or Browserify) to manage dependencies.
  • Overhead
    For smaller projects, using a modular approach might be overkill, introducing unnecessary overhead in terms of setup, configuration, and code management.
  • Learning Curve
    Developers unfamiliar with modular JavaScript may face a learning curve, especially when dealing with module patterns, loaders, and bundlers.
  • Dependency Management
    Relying on multiple modules can lead to complex dependency chains, making it challenging to track and resolve dependencies across different modules.
  • Performance Overhead
    Modular JavaScript can introduce performance overhead if not managed properly, such as loading many small modules individually, leading to increased HTTP requests.

Questions & Answers

As answered by people managing Fideliya and Modular JavaScript.

What makes your product unique?

Fideliya's answer

Most loyalty software hands you a dashboard and bolts a card onto it. Fideliya starts with the card. Every customer carries a branded pass that lives inside Apple Wallet and Google Wallet, right beside their boarding passes and concert tickets. It updates the moment they're scanned, and there is nothing for them to download. It also speaks their language from the start, in English, French, Spanish and Arabic, with full right to left support, so the pass feels made for them rather than translated for them. Very little in this category does both.

How would you describe the primary audience of your product?

Fideliya's answer

The owner who knows her regulars by name. Specialty coffee shops, barbers, salons, spas, gyms, boutiques, the independent restaurant on the corner. People with taste and pride who built something worth coming back to, and who have never had a loyalty tool that matched the care they put into everything else. Fideliya is for them, not for the chains.

Why should a person choose your product over its competitors?

Fideliya's answer

Because your customers never have to think about it. The pass is already in their wallet, their points and rewards move in real time, and they never install an app or create an account. Everything you need lives in one place: points and stamps, a referral code built into every pass, gift cards, honest analytics, and one tap to reach every cardholder at once. It works beautifully in four languages, Arabic included, which most tools quietly skip. Pricing is transparent and in euros, with a free tier, so you can see it for yourself long before you talk to anyone.

What's the story behind your product?

Fideliya's answer

Small businesses are the backbone of every city worth loving, and they lose their most loyal customers in silence. Not to bad service, but to big franchises with apps, points systems, and entire teams built to bring people back. The owner has tools for marketing, for accounting, for bookings. For the regulars, the ones who matter most, only hope. The most loyal customers in the world walk into these places every day and leave without a trace. They deserve better. They just never had the tools to match their heart. Fideliya is that tool.

Which are the primary technologies used for building your product?

Fideliya's answer

Fideliya is built on the two technologies that matter most to the people using it: Apple Wallet, through Apple's PassKit, and the Google Wallet Integration. That's what lets a pass live in a customer's phone, update in real time, and work without an app. The rest sits on a modern, secure web stack chosen for speed and reliability, with bank grade payment and data handling underneath. The wallet integrations are the part you can see. The rest is built to stay out of your way.
